A sprawling, multi-stemmed mat of annual trampweed (Facelis retusa) growing on the sandy shore of Lake Somerville, Texas. This tough winter annual is a member of the aster family and a close relative of native cudweeds. It is easily identified by its narrow, gray-green leaves that feature distinctly blunted or notched tips (retuse) and bright white, woolly undersides. At the center of the plant, there are small, tight flower heads beginning to form at the tips of the stems. Texas, February 28, 2026
A perfectly symmetrical winter basal rosette of a yellowcress (Rorippa species, likely Southern marsh yellowcress, Rorippa teres) blooming on the exposed sandy shore of Lake Somerville. This native wetland pioneer is a member of the mustard family (Brassicaceae). During the cooler months, it forms this flat, circular spray of deeply cut (pinnatifid) leaves to anchor firmly in the shifting sand while maximizing sun exposure and avoiding cold winds. At the very center, the plant has just begun to bolt, producing the tiny, four-petaled yellow flowers characteristic of its family. Texas, February 28, 2026
